Z 9 WWQvJ W Patented Mar. 17, 1936 UNITED STATES rarer OFFICE 5 Claims.

My invention relates to improvements in wall structures for buildings,

One object of this invention is to provide an economically constructed wall structure possessing the inherent quality .of supporting loads throughout the length of the wall structure.

Another object is to provide a wall structure for a building which can be constructed in separate units and assembled quickly and easily on the building site. p

A further object is to provide a firm, durable wall structure which possesses the inherent ability of distributing stresses imposed upon one portion thereof to, adjacent portions and which also possesses an inherent resiliency permitting the wall to sustain pressure directed normally thereto without permanent deformation.

Another object of my invention is to provide in a wall structure a corrugated, reversely curved, or otherwise similarly formed metal sheet of such a formation that it readily transfers the stress imposed on any portion to adjoining portions. The metal sheet is so shaped that, in the formation thereof, the metal in the sheet is worked or stressed approximately equally throughout its entire area, and the metal as a result is substantially constant and uniform in character throughout every part of the sheet.

A further object is to provide a wall structure with an insulation section which not only reduced the heat conductivity through the wall but also strengthens the wall structure and cushions impacts imposed upon the wall.

An additional meritorious characteristic is that my laminated wall structure has its several laminations so secured together and particularly the laminations which are secured to the corrugated metal sheet are so fastened to the crests thereof as to permit flexibility and resiliency of the lamination. of the structure to meet required demands and permit relative movement.

A still further object is to provide a wall struc-- ture for a building which has little heat conductivity, considerable sound absorbing characteristics, and is inexpensive to make.

Further objects and meritorious features of my invention will become apparent from the following description and accompanying drawing wherein like numerals refer to like parts throughoutthe several figures and wherein:

Figure 1 is a perspective of the wall struc-- Figure 3 is a sectional view of a modification illustrating a slightly different manner of assembling the wall structure,

Figure 4*is a sectional view of one formation of the corrugated metal sheet, 5

Figure 5 is a sectional view of another formation of the corrugated metal sheet, and

Figure 6 is a sectional view of another formation of the corrugated metal sheet.

The wall structure is a laminated construction 10 having a corrugated metal sheet forming one of the laminations. As illustrated in the drawing, particularly Figure 1, a metal sheet III has vertical corrugations rolled therein. These corrugations are made up of a continuous succession 15 of alternate reversely curved portions throughout the extent of the metal sheet.

On one side of the corrugated sheet l0 there may be mounted a fiber board I! or any other suitable panel or sheet material for forming the 2 wall surface of a room in a building. In order to secure this panel to the corrugated metal it is preferred that a yieldable, non-hardening adhesive be spread over the crests of the corrugations as indicated at M. This panel may also be secured 25 by means of rivets 0r stitches. A strip of felt or similar material may be used in place of the adhesive in this case. This is to take up variations occurring in fabrication and also to dampen forces being transmitted through the wall structure from layer to layer, I

On the side of the corrugated sheet metal opposite to the panel l2 there is mounteda panel of fiber boards I6 which may be corrugated. This panel in the embodiment disclosed herein consists 5 of a seriesof corrugated and flat fibre boards permanently held together and forming a heat insulation for the wall structure. To permanently but yieldably position this insulation against the corrugated sheet metal non-hardening ad- 40 hesive M or other securing means may be used as previously mentioned. In place of the fiber boards l6 a panel of homogeneous fibrous mate rial or any other substance having insulative qualities may be used. Between the corrugated 5 sections and the panels on either side a plurality of dead air pockets I8 are formed which aid considerably in preventing the transmission of heat and sound through the wall structure.

To form an outside protective coating for the 50 wall structure, a. fiat sheet of metal 20 may be secured to the insulation It by the adhesive 22.

In place of the metal sheeting, paper or any other suitable protective material may be utilized.

In Figure 2 there is illustrated a manner of 55 constructing the wall structure in separate which are later assembled together to form he wall. The laminated construction of the wall is very similar to that in Figure 1. The corrugated metal sheets are cut in separate sections at certain spaced intervals. The edges of these sections may be turned in forming hook like fasteners as indicated at 24. Likewise, the insulation panel I6 is cut into sections equaling in length the corrugated metal sections. These cut off portions are indicated at 26. The sheet metal 20 is formed in slightly larger sections and the overlapping edges 28 are bent inwardly to secure the insulation therebetween. As previously described, suitable yieldable securing means may be used for securing the various parts together into a unitary structure.

After these wall units have been manufactured they may be shipped in separate units to the building site and there assembled together and erected into a wall structure for the building. In the erection of a wall composed of a plurality of wall units such as described, a fastening device comprising a split tube 32 may be used which is slidable behind the fasteners 24 and secures the adjoining wall units together. A similar provision for joining two wall units is provided for the comers. Packing or caulking is provided between the flanges 28 and the fasteners 24 in order to weatherproof the cracks between the wall units and to lessen the heat conductivity through the wall by preventing metal-to-me tal contact.

In Figure 3 a slightly different arrangement for assembling the wall structure together at the building site is illustrated. In this modification the corrugated metal strip is one continuous sheet and may be secured in vertical position before the addition of the insulation to thewall. As shown in Figure 2 the metal sheet 20 has at spaced intervals inwardly extending flanges 28 which in this particular caseextend inwardly as far as the corrugated metal and may be spot welded thereto as at 34. Packing may or may not be provided between the flanges.

Figures 4, 5, and 6 illustrate various corrugated formations which may be used. The formation in Figures 4 and 5 are adapted to support heavy loads while that in Figure 6 is adapted for the support of lighter loads. In the various figures illustrated in the drawing, with the exception of Figure 5, every portion of the convolutions making up the corrugated sheet metal is arcuate. In Figure 5, however, the mid-part of the convolution forms a straight section and the rest or greater portion of the convolution is in curved section.

The wall structure is load supporting in itself.

Every two adjacent corrugations in the metal sheet form a laterally displaced hollow column for supporting the building. There is no need for providing additional vertical supports at the corners or intermediate portions of the building.

When loads are supported by the corrugated metal sheet stresses occur, and the arcuate formation of each portion of the corrugations readily transmit the stresses to adjacent portions of the metal sheet. The absence of sharp angle bends in the corrugated metal enable strains imposed on the wall structure to be spread over the areas adjacent. The nearly constant physical characteristics of the formed section are contributing factors in this connection. and sudden shocks brought to bear against the Pressures used to secure the laminations of the wall together 10 permits relative movement between the various parts of the wall structure when abnormal stresses are encountered. Although not limited to such application the wall structure is peculiarly adaptable to buildings in whose construction the 15 following features are of major importance; ease and speed of erection, high salvage value of materials, and ease of replacement in the case of units damaged during use or in the case of alterations.

Various other modifications of the structure illustrated will be apparent to those skilled in the art and for that reason I intend to limit myself only within the scope of the appended claims.
